BB Curve :: Replying To Text Messages On The 9320?

Well today I had my first couple of messages from a couple of mates of mine, and I am completely confused here just how to reply to them and how you know they have been sent.The manual for the Blackberry Curve 9320 is totally wrong with how it describes to do this, and the regular features that are on every other mobile I have had such as click on something and hit the word reply does not exist on this phone from what I can see.hen I read the persons text message there is a bar underneath for you to type in, and it says press R to reply. I did this and typed something out, and as you do went and pressed the send button. But that brings up a box asking me if I want to call the person. So I thought well lets press the return key on the Qwerty Pad. So I did that, and I have no idea if its sent as I cannot find anywhere on the phone that tells you your message is sent.
